Product Description

Products Description:
Chrome corundum is made of aluminum oxide as the main raw material, adapted to chromium oxide, etc., and is smelted at high temperature. It is pink and dark red. The hardness is similar to that of white corundum, and its toughness is higher than that of white corundum. The chromium corundum produced by our company has good crystallinity, pure color, few impurities, uniform particle size composition, low magnetic content, high packing density and high toughness value, and is well received by domestic and foreign users. The abrasive tools made of it have good durability and high grinding finish. Suitable for precision grinding of measuring tools, machine tool spindles, instrument parts, threaded workpieces and template grinding.
The chrome corundum materials produced by our company can also be used in the coated abrasive production industry. They are mainly used for grinding wood. They can also be used for grinding non-ferrous metals, such as copper, brass, etc. Compared with white corundum, chrome corundum is more It is not brittle and therefore easy to form its smooth surface.
